Lego fans in Leeds are invited to help build a gigantic city crest – made up of 200,704 bricks.
It will be on display at Trinity Leeds until February 21, where people can buy Lego bricks and watch as master builders put the pieces into the mosaic.
Money raised will go to the Lord Mayor’s chosen charity - Specialist Autism Services.
Bricks can be bought for £1 each.
Businesses, groups and organisations can also get their name and logo stamped on the crest by buying a section of bricks.
